A General Strategy To Construct Fluorogenic Probes from Charge-Generation Polymers (CGPs) and AIE-Active Fluorogens through Triggered Complexation

Trip the light of plastic: An aqueous fluorogenic sensing system consisting of selective and specific analyte‐triggerable charge‐generation polymers (CGPs) and a negatively charged aggregation‐induced emission active fluorogen (TPE‐COOH4) is presented. In the presence of a triggering analyte of inte...

Zusammenfassung:Trip the light of plastic: An aqueous fluorogenic sensing system consisting of selective and specific analyte‐triggerable charge‐generation polymers (CGPs) and a negatively charged aggregation‐induced emission active fluorogen (TPE‐COOH4) is presented. In the presence of a triggering analyte of interest, the CGPs undergo electrostatic complexation with TPE‐COOH4 leading to intense fluorescence emission due to the aggregation of TPE‐COOH4.
